President Donald Trump has made border security and illegal immigration an integral part of his actions during his first weeks in office. Multiple executive orders have focused on these issues, and numerous actions have taken place to remove illegal immigrants from the country, particularly those with violent criminal records. Now, barriers are being erected to deter criminal activity along the U.S.-Mexico border.

Federal officials put up World War II-style metal barriers on Wednesday along the border in New Mexico, according to reports. The structures resemble the metal “X-like” anti-tank obstacles known as Panzersperre or Czech hedgehogs that were positioned along the beaches of Normandy during D-Day. A modern-day version of these barriers was placed “on the western slope” of Mount Cristo Rey in Sunland Park, New Mexico.
